00:13
I am an astrophysicist.
0
1317
2492
Eu sou astrofísica.
00:15
I research stellar explosions
across the universe.
1
3833
3055
Pesquiso explosões estelares no Universo,
00:19
But I have a flaw:
2
7603
1200
mas tenho um defeito:
00:21
I'm restless, and I get bored easily.
3
9325
2483
sou impaciente e me entedio facilmente.
00:24
And although as an astrophysicist,
I have the incredible opportunity
4
12356
3196
Apesar de, como astrofísica,
ter a incrível oportunidade
00:27
to study the entire universe,
5
15576
1932
de estudar todo o Universo,
00:29
the thought of doing
only that, always that,
6
17532
3348
a ideia de fazer somente isso, pra sempre,
00:32
makes me feel caged and limited.
7
20904
2231
faz com que eu me sinta presa e limitada.
00:36
What if my issues with
keeping attention and getting bored
8
24762
3914
E se os meus problemas
em manter a atenção e ficar entediada
00:40
were not a flaw, though?
9
28700
1482
não fossem um defeito?
00:42
What if I could turn them into an asset?
10
30206
2667
E se eu pudesse transformá-los
em uma vantagem?
00:45
An astrophysicist cannot
touch or interact with
11
33830
2645
Uma astrofísica não pode tocar
ou interagir com as coisas que estuda.
00:48
the things that she studies.
12
36499
1538
00:50
No way to explode a star in a lab
to figure out why or how it blew up.
13
38061
3713
Não tem como explodir uma estrela
para descobrir como e por que explodiu.
00:54
Just pictures and movies of the sky.
14
42164
2530
São apenas imagens e vídeos do céu.
00:57
Everything we know about the universe,
15
45339
2221
Tudo o que sabemos sobre o Universo,
00:59
from the big bang
that originated space and time,
16
47584
3091
do Big Bang que originou
o espaço e o tempo,
01:02
to the formation and evolution
of stars and galaxies,
17
50699
2794
até a formação e evolução
das estrelas e galáxias,
01:05
to the structure of our own solar system,
18
53517
2460
até a estrutura do nosso sistema solar,
01:08
we figured out studying images of the sky.
19
56001
2800
descobrimos estudando imagens do céu.
01:12
And to study a system
as complex as the entire universe,
20
60006
3952
E para estudar um sistema
tão complexo como o Universo,
01:15
astrophysicists are experts
at extracting simple models and solutions
21
63982
4705
os astrofísicos são especialistas
em extrair modelos e soluções simples
01:20
from large and complex data sets.
22
68711
2339
de conjuntos de dados longos e complexos.
01:23
So what else can I do with this expertise?
23
71705
2425
E o que mais posso fazer
com esta habilidade?
01:28
What if we turned the camera
around towards us?
24
76030
4095
E se virássemos a câmera para nós mesmos?
01:33
At the Urban Observatory,
that is exactly what we are doing.
25
81057
2991
É exatamente o que fazemos
no Urban Observatory.
01:36
Greg Dobler, also an astrophysicist
26
84072
2492
Greg Dobler, também astrofísico
01:38
and my husband,
27
86588
1167
e meu marido,
01:39
created the first urban observatory
in New York University in 2013,
28
87779
3960
criou o primeiro observatório urbano
da Universidade de Nova York em 2013,
01:43
and I joined in 2015.
29
91763
1556
e me juntei a ele em 2015.
01:45
Here are some of the things that we do.
30
93752
1929
Aqui estão algumas coisas que fazemos.
01:48
We take pictures of the city at night
31
96196
2270
Tiramos fotos da cidade à noite
01:50
and study city lights like stars.
32
98490
2589
e estudamos as luzes dela
como se fossem estrelas.
Estudando variações da luz
de acordo com o tempo
01:53
By studying how light changes over time
33
101514
2012
01:55
and the color of astronomical lights,
34
103550
2074
e a cor das luzes astronômicas
01:57
I gain insight about the nature
of exploding stars.
35
105648
2813
tenho uma perspectiva sobre a natureza
das estrelas explosivas.
02:00
By studying city lights the same way,
36
108934
2270
Ao estudar as luzes da cidade
do mesmo modo,
02:03
we can measure and predict how much energy
the city needs and consumes
37
111228
4682
podemos medir e prever quanta energia
a cidade precisa e consome
e ajudar a construir uma rede resiliente
02:07
and help build a resilient grid
38
115934
1847
02:09
that will support the needs
or growing urban environments.
39
117805
3299
que apoiará as necessidades
de ambientes urbanos em crescimento.
02:14
In daytime images,
we capture plumes of pollution.
40
122283
3357
Nestas imagens diurnas,
capturamos plumas de poluição.
02:18
Seventy-five percent
of greenhouse gases in New York City
41
126274
3470
Na cidade de Nova York,
75% dos gases de efeito estufa
02:21
come from a building like this one,
burning oil for heat.
42
129768
3632
vêm de um edifício como este,
que queima óleo para seu aquecimento.
Podemos medir a poluição
com sensores de qualidade do ar.
02:26
You can measure pollution
with air quality sensors.
43
134477
2395
02:28
But imagine putting a sensor
on each New York City building,
44
136896
3842
Mas imaginem colocar um sensor
em cada prédio na cidade de Nova York
02:32
reading in data from a million monitors.
45
140762
2706
e ler dados de um milhão de monitores.
02:35
Imagine the cost.
46
143492
1326
Imaginem o custo.
02:38
With a team of NYU students,
we built a mathematical model,
47
146048
3428
Com uma equipe de estudantes da UNY,
construímos um modelo matemático,
02:41
a neural network that can detect
and track these plumes
48
149500
3389
uma rede neural que pode detectar
e rastrear as plumas no céu da cidade.
02:44
over the New York City skyline.
49
152913
1690
02:46
We can classify them --
50
154627
1482
Podemos classificá-las:
02:48
harmless steam plumes,
white and evanescent;
51
156133
3015
plumas de vapor inofensivo,
branco e evanescente;
02:51
polluting smokestacks,
dark and persistent --
52
159172
3516
fumaça poluente, escura e persistente;
02:54
and provide policy makers
with a map of neighborhood pollution.
53
162712
3759
e fornecer mapas da poluição
para os fiscais ambientais.
02:59
This cross-disciplinary project
created transformational solutions.
54
167777
3889
Este projeto interdisciplinar
criou soluções transformadoras.
03:05
But the data analysis methodologies
we use in astrophysics
55
173942
2913
Mas a metodologia de análise
de dados usada em astrofísica
pode ser aplicada
a qualquer conjunto de dados,
03:08
can be applied to all sorts of data,
56
176879
1961
03:10
not just images.
57
178864
1150
não apenas em imagens.
Fomos convidados a ajudar
um promotor da Califórnia
03:12
We were asked to help
a California district attorney
58
180450
2484
03:14
understand prosecutorial delays
in their jurisdiction.
59
182958
3421
a entender os atrasos
judiciários na jurisdição dele.
Há pessoas em liberdade condicional
ou presas em cadeias,
03:18
There are people on probation
or sitting in jail,
60
186839
2667
03:21
awaiting for trial sometimes for years.
61
189530
2611
em alguns casos esperando
pelo julgamento há anos.
03:24
They wanted to know
what kind of cases dragged on,
62
192165
2444
Eles queriam saber
que tipo de casos se arrastavam,
e tinham um grande conjunto de dados
para exploração e análise,
03:26
and they had a massive data set
to explore to understand it,
63
194633
3124
mas não tinham a habilidade
03:29
but didn't have the expertise
64
197781
1412
03:31
or the instruments
in their office to do so.
65
199217
2548
ou os instrumentos
em seu escritório para fazer isso.
03:33
And that's where we came in.
66
201789
1746
E é aí que entramos.
03:35
I worked with my colleague,
public policy professor Angela Hawken,
67
203559
3397
Trabalhei com minha colega, professora
de políticas públicas Angela Hawken,
03:38
and our team first created
a visual dashboard
68
206980
3486
e nossa equipe criou um painel visual
03:42
for DAs to see and better understand
the prosecution process.
69
210490
3900
para que os promotores entendessem melhor
o processo de acusação.
03:46
But also, we ourselves
analyzed their data,
70
214997
2929
Mas nós mesmos também analisamos os dados,
03:49
looking to see if the duration
of the process
71
217950
2520
procurando ver se a duração do processo
03:52
suffered from social inequalities
in their jurisdiction.
72
220494
3190
sofria por desigualdade social
na jurisdição deles.
03:56
We did so using methods
73
224367
1542
Fizemos isso usando métodos
que eu usaria para classificar
milhares de explosões estelares,
03:57
that I would use to classify
thousands of stellar explosions,
74
225933
2973
04:00
applied to thousands of court cases.
75
228930
2655
aplicado a milhares
de processos judiciais.
04:03
And in doing so,
76
231609
1151
E fazendo isso, criamos um modelo
que pode servir para qualquer jurisdição
04:04
we built a model that can be applied
to other jurisdictions
77
232784
2833
que esteja disposta
a explorar suas tendências.
04:07
who are willing to explore their biases.
78
235641
2190
04:09
These collaborations between
domain experts and astrophysicists
79
237855
3246
Estas colaborações entre
especialistas da área e astrofísicos
04:13
created transformational solutions
80
241125
2055
criaram soluções transformadoras
04:15
to help improve people's quality of life.
81
243204
2400
para melhorar a qualidade
de vida das pessoas.
04:19
But it is a two-way road.
82
247426
1484
Mas é uma via de mão dupla.
Uso minha formação em astrofísica
para a ciência urbana
04:20
I bring my astrophysics background
to urban science,
83
248934
2543
04:23
and I bring what I learn in urban science
back to astrophysics.
84
251501
3841
e levo o que aprendo sobre ciência urbana
de volta para a astrofísica.
04:27
Light echoes:
85
255930
1852
Ecos de luz:
04:30
the reflections of stellar explosions
onto interstellar dust.
86
258461
4567
reflexos de explosões estelares
em poeira interestelar.
04:36
In our images, these reflections appear
as white, evanescent, moving features,
87
264046
5785
Nas imagens, estes reflexos aparecem
como brancos, evanescentes, móveis,
04:41
just like plumes.
88
269855
1150
assim como plumas.
04:43
I am adapting the same models
that detect plumes in city images
89
271363
3895
Estou adaptando os mesmos modelos
que detectam plumas em imagens urbanas
04:47
to detect light echoes
in images of the sky.
90
275282
2928
para detectar ecos de luz
em imagens celestes.
04:52
By exploring the things
that interest and excite me,
91
280290
3293
Ao explorar as coisas
que me interessam e me empolgam,
04:55
reaching outside of my domain,
92
283607
1796
indo além do meu domínio,
04:57
I did turn my restlessness into an asset.
93
285427
2876
transformei minha impaciência
em uma qualidade.
05:01
We, you, all have a unique perspective
that can generate new insight
94
289031
5047
Nós, vocês, todos possuímos
perspectivas únicas
que podem gerar novas descobertas
05:06
and lead to new, unexpected,
transformational solutions.
95
294102
4183
e levar a soluções transformadoras,
inovadoras e inesperadas.
Obrigada.
05:10
Thank you.
